Abstract: The present disclosure relates generally to signal encoding for flexographic printing plates. One aspect is a flexographic, photopolymer printing plate having transparent layers to allow encoded signal printed or laser ablated thereon to be detectable from both sides of the printing plate. Another aspect is a flexographic, photopolymer printing plate having an encoded signal formed in a photocured layer. Still another aspect is a system for tracking such printing plates, including managing location, print impression count, location tracking, etc. Other aspects are described as well.

Abstract: A method and imaging system for creating a motion compensated 3D volumetric derived image from a 4D volumetric medical image is described. The method comprising the steps of: acquiring a 4D volumetric medical image comprising a plurality of 3D volumetric medical images forming a time-series of 3D volumetric medical images representing phases of a physiological motion cycle; determining dominant motion of each 3D volumetric medical image with respect to a reference location that represents a position relative to the motion cycle; resampling each of the 3D volumetric medical images to the reference location to compensate for the determined dominant motion; estimating secondary motion in at least one of each motion compensated 3D volumetric medical images or of each of the original 3D volumetric medical images; and constructing a 3D volumetric derived image by combining data from the motion compensated 3D volumetric images based on the estimated secondary motion.

Abstract: Various implementations disclosed herein include devices, systems, and methods that create a 3D video that includes determining first adjustments (e.g., first transforms) to video frames (e.g., one or more RGB images and depth images per frame) to align content in a coordinate system to remove the effects of capturing camera motion. Various implementations disclosed herein include devices, systems, and methods that playback a 3D video and includes determining second adjustments (e.g., second transforms) to remove the effects of movement of a viewing electronic device relative to a viewing environment during playback of the 3D video. Some implementations distinguish static content and moving content of the video frames to playback only moving objects or facilitate concurrent playback of multiple spatially related 3D videos. The 3D video may include images, audio, or 3D video of a video-capture-device user.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for machine learning image reconstruction. In some implementations, first input data representing the image of the one or more internal structures generated using a first imaging device is provided as input to a first machine learning model having one or more fully-connected layers. First output data generated by the first machine learning model is obtained and the first output data together with second input data representing a second image of the one or more internal structures generated using a second imaging device is provided to a second machine learning model having one or more convolutional layers. Second output data generated by the second machine learning model is obtained and used to generate rendering data that, when processed by a computing device, causes the computing device to output a reconstructed image.

Abstract: A method for calibrating a pitch of a camera on a vehicle is provided. The method includes steps of: a calibration device (a) inputting driving images from the camera into an object detection network to detect objects and generate object detection information and into a lane detection network to detect lanes and generate lane detection information; (b) profiling the object and the lane detection information to generate object profiling information and lane profiling information, inputting the object profiling information into an object-based pitch estimation module to select a first target object and a second target object to generate a first pitch and a second pitch, and (iii) inputting vanishing point detection information and the lane profiling information into a lane-based pitch estimation module to generate a third pitch and a fourth pitch; and (c) inputting the first to the fourth pitches into a pitch-deciding module to generate a decided pitch.

Abstract: A facilitation system for facilitating remote presentation of a physical world includes a first object and an operating environment of the first object. The facilitation system includes a processing system configured to obtain an image frame depicting the physical world, identify a depiction of the first object in the image frame, and obtain a first spatial registration registering an object model with the first object in the physical world. The object model is of the first object. The processing system is further configured to obtain an updated object model corresponding to the object model updated with a current state of the first object, and generate a hybrid frame using the image frame, the first spatial registration, and the updated object model. The hybrid frame includes the image frame with the depiction of the first object replaced by a depiction of the updated object model.
